LTA (Lane Tracing Assist)LTA (Lane Tracing Assist)LTA functionsWhen driving on a road with clear lane lines with the dynamic radar cruise control
operating, lane lines and preceding and surrounding vehicles are detected using the
front camera and radar sensor, and the steering wheel is operated to maintain the
vehicle’s lane position.Use this function only on highways and expressways.If the dynamic radar cruise control is not operating, the function will not operate.In situations where the lane lines are difficult to see or are not visible, such as
when in a traffic jam, support will be provided using the path of preceding and surrounding
vehicles.If the system determines that the steering wheel has not been operated for a certain
amount of time or the steering wheel is not being firmly gripped, the driver will
be alerted and this function will be temporarily canceled.If the steering wheel is firmly gripped, the function will begin operating again.When the function is operating, if the vehicle is likely to depart from its lane,
the driver will be alerted via a display and buzzer.When the buzzer sounds, check the area around the vehicle and carefully operate the
steering wheel to move the vehicle back to the center of the lane.Warning:Before using the LTA systemDo not overly rely on the LTA system. The LTA system is not a system which provides
automated assistance in driving and it is not a system which reduces the amount of
attention necessary for safe driving. The driver is solely responsible for paying
attention to their surroundings and operating the steering wheel as necessary to ensure
safety. Also, the driver is responsible for taking adequate breaks when fatigued,
such as when driving for a long time.Failure to perform appropriate driving operations and pay careful attention may lead
to an accident.When not using the LTA system, turn it off using the LTA switch.When turning off LTAWhen it is necessary to disable the system: When it is necessary to disable the systemNote:Operating conditions of functionThis function is operable when all of the following conditions are met:The LTA system detects lane lines or the path of preceding or surrounding vehicles.The dynamic radar cruise control is operating.The lane width is approximately 10 to 13 ft. (3 to 4 m).The turn signal lever is not being operated.The vehicle is not being driven around a sharp curve.The vehicle is not accelerating or decelerating more than a certain amount.The steering wheel is not being turned with a certain amount of steering force or
more.The hands off steering wheel warning (Hands off steering wheel warning operation) is not operating.The vehicle is being driven in the center of a lane.Temporary cancelation of functionsWhen the operating conditions are no longer met, a function may be temporarily canceled.
However, when the operation conditions are met again, operation of the function will
automatically be restored. (Operating conditions of function)If the operating conditions of a function are no longer met while the function is
operating, a buzzer may sound to indicate that the function has been temporarily canceled.The steering assist operation of the function can be overridden by the steering wheel
operation of the driver.Hands off steering wheel warning operationWhen the system determines that the driver has removed their hands from the steering
wheel, a warning message urging the driver to hold the steering wheel and the symbol
shown in the illustration are displayed on the multi-information display. If the driver
continues to keep their hands off of the steering wheel, the function is temporarily
canceled.When the system detects a steering wheel operation, the warning stops. Always keep
your hands on the steering wheel when using this system, regardless of warnings.Situations in which the hands off steering wheel warning may not operate properlyThe warning may not operate normally depending on the vehicle condition, the operating
status of the steering wheel, and the road surface condition.Vehicles with LCA: The warning may not operate in the following situations even if
the driver has removed their hands from the steering wheel.When an object other than the driver’s hand is touching the steering wheelWhen an object, arm, etc. is near a large portion of the steering wheelSteering wheel operations may not be detected correctly and the warning may operate
in the following situations.When the driver’s hand is rested lightly on the steering wheel while drivingWhen a steering wheel cover is installed*When the driver is wearing gloves*When foreign matter is attached to the steering wheel*When the driver is gripping the wood trim, seam of the leather, spokes, or other part
of the steering wheel that does not have sensors**Vehicles with LCALane departure warning during LTA operationA warning is issued if the vehicle departs from the lane during LTA operation regardless
of the LDA setting.If a steering wheel operation equivalent to changing lanes is detected, the system
will not determine this to be lane departure and it will not issue a warning.Enabling/disabling the systemThe LTA will change between ON/OFF each time the LTA switch is pressed.When the LTA is ON, the LTA indicator will illuminate.Warning:Situations in which the functions may not operate properlyIn the following situations, the functions may not operate properly and the vehicle
may depart from its lane. Do not overly rely on these functions. The driver is solely
responsible for paying attention to their surroundings and operating the steering
wheel as necessary to ensure safety.When a preceding or surrounding vehicle changes lanes or changes course (Your vehicle
may follow the preceding or surrounding vehicle and also change lanes or changes course)When a preceding or surrounding vehicle is swaying (Your vehicle may sway accordingly
and depart from the lane)When a preceding or surrounding vehicle departs from a lane (Your vehicle may follow
the preceding or surrounding vehicle and also depart from the lane)When a preceding or surrounding vehicle is being driven extremely close to the left/right
lane line (Your vehicle may follow the preceding or surrounding vehicle accordingly
and depart from the lane)When there are moving objects or structures in the surrounding area (Depending on
the position of the moving object or structure relative to your vehicle, your vehicle
may sway)When the vehicle is struck by a crosswind or the turbulence of other nearby vehiclesSituations in which the sensors and the systems may not operate properly: Situations in which the sensors and the systems may not operate properlySituations in which the lane may not be detected: Situations in which the lane may not be detectedLTA indicatorOperation display of steering wheel operation supportThe operating state of the LTA system is indicated.
